"There have been some recent changes as per our list of fees published on our website.

"Priority boarding, which allows customers to bring two pieces of hand luggage on board with them and board the plane first, costs €5/€6 (depending on the route) at the time of booking and €6/€7 (depending on the route) when added to a booking.”

The airline first made the decision to charge for carry-ons because they claimed too many passengers were trying to take wheely suitcases on-board, which was causing boarding and flight delays.

Kenny said: "This will speed up the boarding of flights and eliminate flight delays being caused by not having sufficient overhead cabin space on busy flights to accommodate over 360 (182 customers x 2 bags) carry-on bags."

But earlier this month, company boss Michael O'Leary warned that the airline could change their bag policy again because too many passengers were checking their bags into the hold for free.

He said: "There are many flights where we're now having to put 100 or 120 gate bags free of charge into the hold.

"If that continues to build, it's something we may have to look at again."

Originally, all passengers had a week to check in and that was then cut to four days, with the latest change slashing the allowance to two days for those unwilling to pay for the budget airline's added extras.

The 48-hour window will close two hours before the flight's scheduled departure time.
